War to End All Wars is the thirteenth studio album by guitarist Yngwie Malmsteen, released on 7 November 2000 through Pony Canyon (Japan), Spitfire Records (United States) and DreamCatcher Records (Europe). While on tour for this album, singer Mark Boals left the band and was replaced for a brief period by Jorn Lande; however, Boals returned to finish the tour. The instrumental song "Molto Arpeggiosa" is often mislabelled as "Arpeggios from Hell". The phrase " the war to end all wars" was historically used as a description of World War I, especially in the period from 1918 to 1939.
